2 Claims.

My invention relates to a wrench for placing or removing nuts fromthreaded bolts, and means to turn the wrench.

The object of my invention is to provide an electric luminating systemcarried by a wrench mechanism, the system consisting of a dry cellbattery, lamp, and switch to make and break the current, whereby amechanic is able to work in dark places or under subdued lightconditions, rendering it possible to quickly locate a bolt head or nutto which the wrench jaws or socketed head is to be applied.

A further object of my invention is to provide the lamp so that thelight rays therefrom are concealed from the eyes of the workman, andbeing directed axial with and through the wrench socket to search forand focus upon the bolt head or nut to which the wrench will be applied.

These and other objects will hereinafter be more fully explained,reference being had to the accompanying drawing forming a part of thisspecification in which like characters will apply to like parts in thedifferent views.

Referring to the drawing:

Fig. 1 is a side View of the mechanism, parts removed for convenience ofillustration, the socket wrench being removed.

Fig. 2 is an end view of Fig. 1, opposite the lamp.

Fig. 3 is a side View of the mechanism transverse to that shown in Fig.1, parts removed for convenience of illustration, and the rockingmovement of the wrench head, illustrated by dotted lines, also a nutupon which the rays of the lamp are focused.

Fig. 4 is an end view showing a 12 point wrench and lamp concentricallypositioned.

Fig. 5 is a modification of the switch mechanism, the wrench removed.Fig. 6 is an end view of the lamp and of Fig. 5.

The invention herein disclosed consists of a stock I, axially bored toreceive a battery 2, removably seated therein, and being secured by athreaded stud 3, the inner end of which is frusto conical to engage uponthe adjacent end of the battery, as conducting means for one side of thecurrent through the stock to a switch 4, the said switch having a throwlever 5 to make and break the current that is conducted to a lamp 6,through the medium of an insulated Wire 1, that is connected to saidswitch, the said wire extending through the bore of the stock andemerging therefrom as at A, and extending therealong to a pin 8 that isaxially bored as at A to receive the end of said wire positioned thereinand extending therefrom through an aperture 9, in the shell of said pinso that the end of said wire is in contact with the base B of the saidlamp for the purpose heretofore described. One end of the said stock isbifurcated, having two legs C and D between which a rockably mountedhead H3, is pivotedly carried through the medium of the said pin 8 abovedescribed, the said pin being rigidly connected to the head and turningtherewith, by which means the end of the wire will remain in contactwith the base of the lamp when the said head is turned to a desiredangle. Note that the inner end of the head is arcuate in form, the radiiof which are from the center of the pin, and to secure the head axiallyextending from the stock, there is arranged a ball-headed pin I I,seating in a socket positioned in the arced portion of the head, butfree to move therefrom when said head is turned in either direction, thesaid pin being spring tensioned toward the head, as shown by dottedlines. The outer end of the head is rectangular in form as shown at D inFig. 4, the purpose of which is to seat snugly in a rectangular openingof a socket wrench l2, as shown in Figs. 3 and 4, the said wrenchelement having twelve points to engage with the corners of a nut, itbeing understood that the latter will vary in size to conform to nuts ofdifferent dimension. The said head is bored axial with its rectangularportion, and being threaded to receive the base of the lamp as shown inFigs. 1 and 5, by which means the said lamp is removable andreplaceable, and being adapted to focus its rays outward through thesaid wrench element upon a nut or the like as shown in Fig. 3. The lightfeature also functions to search for such nut or head of a bolt insubdued light, the purpose of which is to avoid other means ofillumination when such would not be available. In other words, myinvention with respect to an illuminating means will take the place ofother lighting means heretofore employed. The other end of the stock isbored transversely to receive a lever l3, loosely engaging therein andfunctioning as turning means for the stock of the mechanism. It will beunderstood, however, that the said stock will function as a handle toturn the wrench when the latter is positioned at right angles thereto,as shown by dotted lines EE. In Fig. 5 is shown a threaded stud I4,having an extension 15 inward to contact with the end of the saidbattery as closing means for the circuit, and tobreak the circuit thesaid stud is screwed outward therefrom through the medium of an outwardextension l6, gripping it with the fingers to turn the While I haveshown a hexagon stock, the

same may be cylindrical or other polygonal shape, and other means forturning the stock and wrench may be accomplished by the application ofany desired method to grip the same, and such other modification may beemployed as lies within the scope of the appended claims.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a wrench, a stock axially bored from one end to near the otherend, a head pivotally carried at the last named end of the stock, thehead being axially bored and threaded and an electric lamp threadedlyengaging in the bore, a battery carried in the bore of the stock andmeans to secure the battery therein and ground the same to the stock, aswitch positioned on the stock and movable to and from contact with itsadjacent end of the battery, and a wire connecting the switch with thelamp to illuminate the same when the switch is closed with the battery,a

socket wrench to engage with the head and surrounding the lamp for thepurpose specified.

2. In a wrench mechanism of the class described, comprising a stock anda head pivotally mounted to one end of the stock through the medium of ahollow pin, the head axially bored and threaded from the outer end,inward toward the pin, the pin being apertured in alignment with thebore, an electric lamp threadedly engaging in the head, the outer end ofthe head adapted to receive a socket point engaging wrench through whichrays of the lamp will extend, an insulated wire extending into thehollow of the pin and through the aperture, so that the open end of thewire is in contact with the base of the lamp, the other portion of thewire extending into the hollow of the stock, and a switch elementcarried by the stock'and being connected to the other open end of thewire, a battery positioned in the bore of the stock and having one endin close proximity to the switch, the said switch, when moved in contactwith the battery is circuit closing means for the lamp, a threaded studto engage in the bore of the stock and being in contact with the end ofthe battery to ground said battery to the stock.
